There is a heavy influence in Southern Mindanao in their martial arts from Indonesia. Many people do not realize there is a Karambit (also called, Lihok or Lijok or Lejok) in the Philippines from that area. It has quite a reputation actually. It is a weapon of deception being it is concealed and hidden so easily. It was a great assassination weapon. Women would carry a Karambit for self defense purposes also.
